Directed by Gary Ross (Seabiscuit)
Based on the novel by Suzanne Collins

IMDB synopsis:

In a not-too-distant future, North America has collapsed, weakened by drought, fire, famine, and war to be replaced by Panem, a country divided into the Capitol and 12 districts. Each year two young representatives from each district are selected by lottery to participate in The Hunger Games. Part entertainment, part brutal intimidation of the subjugated districts, the televised games are broadcast throughout Panem. As the 24 participants are forced to eliminate their competitors, literally, with all citizens required to watch. When 16-year-old Katniss' young sister, Prim, is selected as the mining district's female representative, Katniss volunteers to take her place. She and her male counterpart Peeta, will be pitted against bigger, stronger representatives who have trained for this their whole lives.

Some cinema buffs may note the resemblance to Kinji Fukasaku's 2000 Japanese cult hit 'Battle Royale'...guess we'll just have to wait and see...
